ACTUATING-BAR CONTROL FOR ACCOUNTING MACHINES.

Application led November 14, 1918, Serial No. 262,586.

Thisinvention relates to improvements in vprinting accounting machines, these ii.-

provements being applied to accounting ma chines having registering and printing elements comprising type sectors and reciprocating',rack bars positively driven for operating the type sectors. Such a machine is Y grade direction atterthey have been moved t' mfardly to printing position. One object oi' the present invention is to provide improved and efficient means forpreventing 's resnlt,wlicn items are printed and also en totals are printed.

ln said machine, veach of the racl bars is provided With a depressible abutment lever provided with an abutment. against Which,

l carrying mechanism are provided in 1which igher order so that an additional spacci-s registered on the associated accumulator. lNhen this operation takes place it desirable to avoid the possibility that any but the. desired rack barbe kicked Renewed March 21, 1925.

back, Therefore, another obiectotI the invention is to provide means Which Will prevent the accidental moving bach ot the rack bar except when carrving is to be effected thereby. l

After the above desired carrving has been effected it is necessary to restore the rack bars to their normal position; and another obJect of the invention is to provide a convenlent and eiiicient means for effectinothis restoring. o

'Another object of the invention is to provide means for positively restoring the abut ment levers to depressed position after they have 'been raised to driving engagement with the drive bar.

Another object of the invention is to provide lined zero stop tor holding the rack bars in Zero position until they are lifted therefrom for the registering` et a numeral.

Another object is to provide means ior locking any individual abutment `lever depressed so that it will not be driven forward by'the drive bar. This locking has for its object to accomplish the Well-known splitting of the accounting mechanism into Lseparate columns.

These and other objects Will appear as the description proceeds; and While herein l have described minute details of the invention, the invention is not limited to these, since the details oi construction and coinbination may be greatly,v varied without departing `from the spirit and scope ot the invention as claimed,

ln the said copending application, means are shown for feeding perforated cards tol ln the present specitication, the left hand end of the machine, as shown in Fig. l, is considered the forward end ofthe machine.

Referring more particularly to the drawings of the present specification, there is shown the cheek plates l0, between which cheek plates variousmechanisms of one unit of the accounting machine are mounted,`these cheek plates being carried on a suitable base orframe not shown. Between said cheek plates there are mounted a plurality of rows of numeral stop pins ll vertically slidable in f' upper guide plates l2 and lowerguide plates 13 carried upon cross plates 14 mounted-upon the cheek plates.

the purpose of preventing the return of rack bars20 when taking a total, as will be describedin detail later. Y

The forward part of the upper edge of each rack bar 2O is provided with a series of teeth 28 adaptedl to mesh with a gear wheel 29 fixed upon the side of each type sector 30 rotatably mounted upon the sector or register shaft 3l.' Each sector isprovioed with a series of printing type'32 and a series of gear teeth 33 adapted to engage with the accumulator wheels 34 (Fig. 5). v

Against one side of each rack bar 2O there is disposed an abutment lever 40 pivloted at its forward end to the rackbar and Vextending rearwardly along -said rack bar above said rodv 22. In Figs. l and 11 the abutment lever 4() is shown in depressed potion.

Fig. l2 it is in raised posi- The intermediate part of the abut-ment lever 40 is slightly laterally odset forming a part to the `iside of the rack bar 20 and provided at its forward end with a lateral projecting pin 45 engaging in a small longif The lower-end of the elbow lever is provided with a laterally turned end'forniing an inclined Yface 48 and a forward shoulder 49.

The rack bar 2O is vprovided with an upstanding abutment provided with an inwardlydisposedshoulder 5G, which when the abutmentlever is raised, is opposed to rand slightly spaced from the outwardly disposed shoulder 51,' formed by an upstanding'abutment on the abutment lever. Between said shoulders-is disposed a reciprocating rack bar 52 which is reciprocated forward land backward by suitable means controlled. by a suitable cam control means, as explained in said copending application.V

Then the transverse bar 52 is retratfted,` it engages the shoulder 50 and retracts the rack bars, the abutment leversv and the elbow levers, whereupon said inclined face 53 of the` abutment leven-engages Athe fixed Zero stop 54 and permits the shoulder 55 to engage the outer face of thev zero stop.

Whenthe vtransverse drive bar 52 commences its forward movement, if no numeral stop 11 associated with any rack bar and associated abutment lever is raised, the shoulder 5l remains depressed and the drive bar passes on without moving the rack bar. If,

however, in accordance with the perfora-Y rnient to assume a movement "tlieyare fully described in said copeiidiiio vla), each provided .with a slot, guide the acciiilulator ca riag'e in its remence's its forward movement. The raising of an abutment lever Ll0 brings the shoulder l in front of the drive bar 52 which drives Vthe rack bar 2O and said abutment lever forward on its forvvart movement until the shoulder 49 `comes into Contact with the pressed.

This forward movement of a rack bar 2O rocks the type sector 30 and bringsvthe type 32 corresponding to the raised stop pin in front of the reciprocating` printing carriage described in saidV copendiiig` application, Whereup the printing carriage is moved toward the type and presses the paper carried thereon against the type and prints the number corresponding to the raised pin.

As is obvious by an inspection of Fig. l, the part of the type sector carryingY the t l is morer remote from center or' the tyiL sector than the other parts thereof; Weight of this part tends after the transverse bar 52 has vbeen freed, to cansn the type 7ivi ich is i i clockwise in the said FiO. l'. Duringitie registering of items, this anti-clockwise vmovement is prevented by the. engaeifeinent of the outvvai'dlf,7 and 'doivnivardlgvi shoulder 57 with the raised stop pin li. when the abutment lever is depressed as above noted. This is shown in dot and dash position in Fig. l2. Y

Thev accumulating mechanism or accumulator is carried in an accumulator carriage 65 disposed between "the cheek plates 10.

Between the restoring levers 101 is carried a supporting rod 109 from which hang the pendant links 110 provided with slots 111 receiving said supporting rod. The upper portion of these pendant links are also provided with laterally turned lips 112 adapted vto engage over the 'associated settable levers and tohold the pendant'links in raised position When the settablelevers are in the position oi Fig. 17 but to permit the pendant links to be drawn down under the'action of the springs 114, when the end S9 of the settable levers are raised by the cani tace 8-1. To the lower end of each pendant link 110 is pivotally connected the rearward end ot a carrying bar 116, the forward end of which bar is pivo'tally connected to the lower end ot the carrying lever 117 yieldably held forward by ineans of a spring 118 strained between the hook 119 of the carrying lever and the I hook plate 120 carried between the side plates of the carriage. A spring 121 stra-ined between said hook plate'120 and a hook 122 on the rear rend of the restoring levers 104 yieldably holds Vthe rear ends. oi' the restoring levers in depressed position.V The VVcoinb plate 123 holds`l the rear part of the carrying bars 116 in spaced relation.

Suitable means, described in said copending application, are provided for reciprocating said levers 139 to causesaid cani plate to be reciprocated forwardly when carrying is to be effected.A

The lower end of each` detent lever 91 (Figs. 1 and 13) is provided with an outwardly projecting` tail 150 having a laterally turned end 151 adapted to engage beiind a lug 152 on the upper edge of the rack bar 20 of the next higher order. YVhen a settable lever 87 is not set as when no carrying from its accumulator wheel is-to be effected, th detent lever 91 remains in the position of Fig. 1, and the laterally turned end 151 prevents the accidental rearward' movement ofthe rack bar.

When this rocking of the settable lever takes y place, `the detentlever 91 raises the laterally turned end, 151 from the lug 152 from said rack bar of the next higher order due to the tension of spring 96. The upper end ot said detent lever at the saine time engages over the rear end of the settable levei` andl holds the same in set position until the cani plate 128 is reciprocated forwardly,and engaging thev rollers 126 rocks the carrying levers 117 so that the Vcarrying bars 116 are inoved rearward. Those carrying bars which have been lowered as thus explained will, during this rearward movement', engage `the shoulder() of the rack bar 2O ofthe'neiit higher order,

and thereby rotate the type sector and the associated accumulator wheel oi said next higher order, onel tooth space, so as to add thereto one unit, which thereby eifectsthe After the carrying has been carrying.

`releasing rod whereby the settable levers spring 118. At the saine t-ime, the restoring levers 160 tulcruined on the inner face of the cheek plates 10 are engaged by pins 161 carried on the reciprocating racks 131 and projecting through the slots 163. This engagement causes the restoring rod 164 lcarried by the lower ends of said levers 160 to engage and restore to normal position any rack bar that has been kicked backduring carrying but does notaffect the position o'ltlie accumulator wheel 34 since it is now out of engagement with the teeth Tlie't'otal taking mechanism.

During the printing and accumulating of an item, the accumulator is moved forwardly so as to mesh with the teeth 33 on the type sectors during the rearward or return stroke of the rack-bars. When a total is taken, the reverse is the case and the accumulator is moved 'forward during the torward initial stroke of the rack bars and the drive bai' 52. This reversal ot the cycle of they Vreciprocation and the mechanism for bringing it about is fully described in said copending application.

Then the total taking process is initiated, the stop pins 11 and the abutment levers 40 are in depressed position and it is necessary that the abutment levers be raised in order to clear the fixed Zerostop and also to have driving engagement with the drive bar.

For this' purpose there is provided a pair of U-levers 170 ulcruined on the rod 171 carried upon ears 172 stamped from the outer cross plate 14. Between the upper end of the supporting arms 17 4 of said U-levers is supported the raising rod 175 adapted to engage the lower edge of the abutment levers. This rod may be yieldably raisedby means ot the springs 176 strained between the hooks 178 on the inner cross plate and hook 179 carried by the lift- 5 is pivotally secured a link 185 having its forward end connected to a pin 186 passing through a slot 187 inthe cheek plate and carried by a vertical lever 188. y The lower end of the vertical lever is rounded and engages in a cam slot 189 (Fig. 10) disposed `iii the active end ot' the total shift lever.

The inner end of the total shift lever is fnlci'uiiied on a pivot post 193 (Fig. 9) mounted upon the base or any suitable xed part of the machine. Secured below and spaced from the total shift lever is the supporting plate 195 provided with downturiied ends 196 and 198, and spaced from the total shift lever by means ot spacing posts 200. Between the lever and the supporting plate is secured a spring housing 201 in which is slidably disposed a plunger 203 provided with a plunger head 204 passing through the shift lever and engaging in the shitting grove 206 ol the shitting cam 207 mounted on the shaft 208.

The plunger is yieldably moved into said engagement with cam groove 206 by means of a spring 210 disposed in said housing and compressed between the supporting plate 195 and collar 211 carried at the lower end of the plunger head. The plunger is noi'- iiially held out of engagement by means of an elboiy pawl 212 pivotally mounted upon the bracket 213 carried on the supporting` plate and provided with an end projection 214 adapted to snap behind the retaining head 215 on the end ot the plunger 203 under the influence of a spring 217 strained between said -elbow pawl and the downturned arm 198. The downturned arm 196 carries a terminal block 216 on which is secured the outer easing of a 1flexible connection of the total cables 219 leading from the designation change sensing mechanism and the total card operated total mechanism.

lVhen a total is to be taken, the terminal pin of the inner wires of one of these-cables operates the elbow pawl 212 releasing the retaining head 215 whereupon the plunger is thrown into the shifting groove 206.v

This shitting groove is spiral in forni and causes the total shift lever to shift rearwardly, moving the lower end of the vertical lever 188 toward the stop pins, and moving the upper end oIP the vertical lever in the opposite direction, thus drawing the latch plate` 181 out of the notch 183 and permitting the spring 176 to move the raising rod 175 to raise the abutment levers 40 until the shoulders clear the fixed zero stop, and the shoulder 51 gets iii front of the drive bar 52, whereby the rack bars are driven forward as shown iii Fig. 15.

The rack bars are carried forward by the transverse bar 52 until the radial face 83 ot' the accumulator wheels engages the rear face of the lower end 89 of the horizontal levers 87. Since all oit the accumulator wheels 34 will not revolve the sani-c distance,

and "since it :is necessary thatl the bar 52 move to the limit or its forward movement, means are provided for releasing the bar `52 fromthe shoulders 51 of suoli rack bars as have reached their limit of movement due to engagementof'faces 83 with the ends 89 .of levers 87. When this engagement takes place the roller 81of each accumulator Awheel (Fig. engages with a rounded pro'- jection220 (Fig. 6) on a vertically movable bracket 221. The brackets 221 are provided with a lowerengaging roller 223 and are pivoted on artransverse rod v224 mounted uplon the cheek plates 10 of the machine W ereby substantially vertical movement is permittedV to the brackets andthe rollers carried thereon. When the rounded projection 220 is engaged by the rollers 81 just explained, the rollers 223 engage and-lower v type properly aligned, an aligning bar 260 30"' said end pieces.

is provided which engages between teet 33 ofthe sector V30 at this time.'

The lower part of thebracket 220 is extended to form a. spacing piece 227 adapted to engage between the abutment 'levers and the rack bar of the next higher order to hold them and the `bracliets noperly'spaced at this point. t

Alfter Vthe rack bars have been positioned as above described, the raising rod 17 5 is lowered by the engagement of the projections 230, on the supporting arms, bythe pin 231 carried on the active end of the restoring lever232fulcrumed on the rod 234 and provided at its mot-ive end with a roller 235 engaging inthecam groove 236. This permits the-latch plate 181 Yto be Vmoved back intov the notch` 183 under the action of the total shift lever 190. y Rael@ Y Zim- /toZcZ/ng mechanism.

Since duringthe total taking operation, noV stop pin 11 is raised, additional-provision .isY made for preventing retrograde movement by the rack bars. Y Y

Pivoted on the ears 240 (Fig. 2) of the upper plate is a pawl frame 241 comprising end 1pieces 242 andy a comb plate 243 between the teeth of which are disposed pawls 244 mounted on the fulcrum rod 245 carried in o The active ends of said pawls areindividually yieldably held upward by springs 246 strained between the outer ends of the of the comb plate.

Figs. 2 and 8 show the mechanism for holding out of operation a rack barand associated type sector so that they will not be operatedby the drive bar 52 to set up numerals von the type sector. f

This mechanism, as shown, comprise a slide-bar 280 slidably received on a side face of the rear extension 281 ofthe abutment.'

projecting from the abutment levers. Said 1 c q Y slide bars have their inner ends laterally oftset as at 285 lto receive the rear'end of the rack bar 2O between the olf-set portion and the abutment lever. The end of the rack f bar is provided with a notch 286 in which engages a locking pin 287 fixed on the inner face of the off-set portion of the slide bar. The slide may be manipulated by means of the pin 288. Y When the slide bar is in rearward posit-ion,

the' abutment lever functions normally.v

l,"Vhen the slide baris in forward position the abutment lever is held against upward movement into driving engagement with the drive bar 52 or out of engagement with the zero stop. y' i The various operations have been fully described liereinbefore except the'following, which will Vbe readily understood from vthe foregoing and need. now be only brieilv summarized as follows: u

As the perforated cards are fed throuh the machine, for each column a pin llis either raisedor not raised, depending noon the perforation of the column. Vlfthe Lc`ollofi vumn has a kZero `perforation then neither a stop pinll nor an abutment lever is raised, and the drive barf 52l remains free. If a numeral stop pin is raised, the abutment lever is also raised, the reciprocating transverse bar 52ybeing in its rear position of movement; and y the rearwardly disposed shoulder 51 of theabutment lever Ll0 disposed in front of the transverse bar. The transverse bar then moves forwardly until the shoulder i9 of the elbow lever is forced into contact with the rear face of the raised stoppin 11,- thus forcing down the abut# ient bar and the rearwardly *facingv shoulder 51, permitting the transverse bar 52 to travel free. Any movement of the rack bar which has then taken place -is determined' b v the position of the stop pin then raised, and this movement is communicated to the type sector whereby the type is positioned for printing. As this forward movement of the raclai bars takes place the shoulder 5"? engages the raised stop pin and prevents any retrograde movement of thel rack bars or the type ,sectors afterthe transverse bar 52 has been freed. Before the printing takes place the locking and alining bar 260 engages between the 'teeth l 33 and holds the type sectors locked and alined while the printing carriage forces the paper against the type. After the printing takes place the transverse bar 52 commences its rearward movement and beforel it has enOaged the forwardly disposed shoulder 50, the locking and alining bar 260 is moved out of contact with'the teeth 33, thestop pins 11 lowered, and the rack bars are retracted -bv the transverse bar 52 engaging the shoulder 50.

When a total is taken the pins 11 are not raised, but the latch plate 181 is retracted and the raising rod 175 raises the abutment levers. At the Ybeginning of the forward movement ofthe transverse bar 52, the abutc ment levers el@ are held raised by means of the spring 176 until the accumulator' wheels which are all thenin mesh with the type sectors, turn in anti-clockwisev direction until the abrupt shoulder 83 of the accumulator wheels engages the lower end 89 of the horizontal lever. At this instant, the projecting roller 8ll engages the projection 220, and the roller 223 depresses the abutment levers i and permits the transverse bar 52to pass on free. At the same time the pawls 244 move to operative position and prevent retrograde movement of the rack bars.
